Some things in life are more important than the others. The same thing applies to Android where certain notifications like SMS messages, Emails, and other forms of communication are more important than alerts from games and news applications.

When we want something to be seen first, we generally pin it. You can find many stickies in almost every forum here on XDA, and they generally contain quite a bit of helpful information. If you ever wanted to pin a certain notification, you can now do so.

XDA Forum Moderator GermainZ wrote an Xposed module that allows you to pin or unpin notifications. You can do this by long-pressing a notification. When pinned, your notifications will remain even when the rest are cleared. It's a simple, yet useful module that prevents you from accidentally missing important messages when getting rid of the useless ones. Unfortunately, it must be noted that this module can't be combined with XhaloFloatingWindow by XDA Recognized Developer zst123, as it will likely crash.

To keep your important notifications pinned, visit the module thread and give this a whirl. There, you will find important information, the module's source code, and download instructions.
